The Effect of Prime Time Television Ethnic/Racial Stereotypes on Latino and Black Americans: A Longitudinal National Level Study

Much is known about the negative consequences of exposure to ethnic/racial stereotypes in the media, on White audiences. However, there is substantially less research addressing the effects of such media content on members of racial/ethnic minority groups. The present study examines this question using repeated cross-sectional national level data alongside a content analysis of top prime time shows between 1987 and 2008. Multi-level modeling analyses reveal that media representations of Latinos and Blacks were associated with Latinos’ and Blacks’ ingroup attitudes, however effects on attitudes towards Whites were not significant.     

Dissecting “Peer Presence” and “Decisions” to Deepen Understanding of Peer Influence on Adolescent Risky Choice

This study evaluated the aspects of complex decisions influenced by peers, and components of peer involvement influential to adolescents’ risky decisions. Participants (N = 140) aged 13–25 completed the Columbia Card Task (CCT), a risky choice task, isolating deliberation-reliant and affect-reliant decisions while alone, while a friend monitors choices, and while a friend is merely present. There is no condition in which a nonfriend peer is present. Results demonstrated the risk-increasing peer effect occurred in the youngest participants in the cold CCT and middle-late adolescents in the hot CCT, whereas other ages and contexts showed a risk-decreasing peer effect. Mere presence was not sufficient to influence risky behavior. These boundaries in age, decision, and peer involvement constrain prevailing models of adolescent peer influence.     

“If They're Trying to Say Something About My Culture … I'm Confused”: Recognizing and Resisting Authenticity in Latino-Themed Television

The television landscape has expanded to include an ever-increasing crop of culturally themed programs aimed at the Latina/o audience. Assumptions about the audience have shaped this trend, resulting in questions about the effectiveness of niche programming to satisfy viewer taste. This project investigates LatiNation with specific focus on the differences in the reception process based on participants' connection to their ethnic identity. In-depth interviews were conducted with self-identified Latina/o students who were also given a survey with scaled items to measure their connection to their ethnic identity. In general, the findings indicate that audience members produce varied readings of the text showing the participants actively negotiate identity by using LatiNation as an opportunity to both embrace and critique Latinidad.     

Identification of a nonlinear dynamic biological model using the dominant parameter selection method

The identification of nonlinear models sometimes encounters problems because of the limited amount of available measurements in combination with a large number of uncertain model parameters to be identified. E.g., the determination of the chemical composition of a lettuce crop is a rather expensive procedure; thus the number of experimental measurements is limited. As a result, the number of parameters of the dynamic model that can be successively identified is also limited, and the subset of the parameters to be identified must be chosen in a reasonable way.Parameter estimation for an extended nonlinear three-state model for lettuce growth in greenhouses is presented in this paper. The varying structural nitrogen concentration and water contents are the new elements included in the model. The dominant parameter selection (DPS) method was used to select a suitable set of identifiable parameters. The resulting calibrated model predicts quite well the experimental data which also include observations with severe nitrogen stress.     

Inter-disciplinarity in sport sciences: The neuroscience example*

Abstract

Sport science is a relatively recent domain of research born from the interactions of different disciplines related to sport. According to the European College of sport science (http://sport-science.org): “scientific excellence in sport science is based on disciplinary competence embedded in the understanding that its essence lies in its multi- and interdisciplinary character”. In this respect, the scientific domain of neuroscience has been developed within such a framework. Influenced by the apparent homogeneity of this scientific domain, the present paper reviews three important research topics in sport from a neuroscientific perspective. These topics concern the relationship between mind and motor action, the effects of cognition on motor performance, and the study of certain mental states (such as the “flow” effect, see below) and motor control issues to understand, for example, the neural substrates of the vertical squat jump. Based on the few extensive examples shown in this review, we argue that by adopting an interdisciplinary paradigm, sport science can emulate neuroscience in becoming a mono-discipline.     

Theory and practice in self‐esteem enhancement: Circle‐Time and efficacy‐based approaches—a controlled evaluation

There are differences of opinion about self‐esteem enhancement in the classroom; these differences exist at both conceptual and practical levels. The aim of this study was to ascertain whether techniques employed by primary school teachers as a day‐to‐day part of their teaching can have measurable effects on the self‐esteem of their pupils. Two different approaches to self‐esteem enhancement in primary classes were evaluated. The participants were 519 primary school children and their teachers (n = 21). Circle‐Time and efficacy‐based approaches were compared with a control condition over a four‐month period. On two self‐report measures of self‐esteem, gains were found for both experimental conditions, but not for the controls. Significant sub‐scale differences suggested that the two approaches achieved their effects in different ways, consistent with a two‐dimensional model of self‐esteem. Circle‐Time methodology, focusing on the creation of a climate in which individuals are respected and valued, is more likely to help children to develop a sense of self‐worth. On the other hand, an efficacy‐based approach tends to focus on the achievement of performance goals, and is thus more likely to develop the self‐competence dimension. It is argued that we should now reconsider how we think about self‐esteem enhancement in primary classrooms.
